General Knowledge — Chapter 2

Geography Superlatives & Features — Largest, Longest, Highest, Deepest

Why this chapter matters: superlatives are the single most bankable GK habit in one-paper exams — a paper-setter who wants a quick, markable question reaches for “largest”, “longest” or “highest” first. Our verified banks hold 771 questions matching this topic: straits and canals (108) — above all the Suez Canal and the Strait of Malacca — lakes (91) and rivers (89) — above all the Nile–Amazon pair, the Caspian–Baikal–Superior trio and the Indus system — mountains and waterfalls (84), islands and peninsulas (62), deserts (51), and 286 further superlatives (oceans, continents, plateaus, ranges, glaciers, coastlines). Learn this chapter as a set of tables, not a story: the master table in Section 2 is the revision sheet, and the feature sections behind it give each answer its one-line reason.

Exam Trend box

• 🔁 Most repeated: the superlative families themselves — 771 verified bank questions ask for a largest, longest, highest or deepest, so the master table in Section 2 is the chapter’s core.
• 🆕 Newly appeared: the 2025 largest-cities year retrospective table (Section 8A) — the UN’s 2025 ranking that moved the “largest city in the world” answer from Tokyo to Jakarta. No 🔁 or ⭐ mark is claimed for the table itself: it rests on one year’s CA-bank rows, below both 🔁 limbs.

1. How to read a superlative question (read this first)

Papers do not ask “biggest” in the abstract — they ask biggest by a stated measure, and the measure changes the answer. Four distinctions carry this whole chapter:

• Longest ≠ largest. The Nile is the longest river in the world; the Amazon is the largest river — largest by volume of water discharged. A question that says “longest” wants the Nile; one that says “largest” wants the Amazon. The same split runs through lakes: Caspian is the largest lake by area, Superior is the largest freshwater lake by surface area, Baikal is the largest freshwater lake by volume — three different answers, all correct, each to its own wording.
• Hot desert ≠ desert. The Sahara is the largest hot desert — and the answer our banks key for “largest desert of the world”. If Antarctica is among the options, it is the largest desert of all (a cold desert); Chapter 1 already gave you that exam tip, and it is repeated in the Traps below because papers keep testing it.
• Highest ≠ tallest structure, deepest ≠ largest. Baikal is the deepest lake but only the seventh-largest by surface area. Angel Falls is the highest waterfall, but Niagara is the famous one — and the one papers ask about borders, not height.
• Bank answer first. Where a modern atlas and our banks disagree (the Caspian’s area, the Suez Canal’s length, the highest plateau), this chapter teaches the bank answer in the core text and puts the variant in Traps & confusions — because the paper is marked against the bank’s key, not the atlas.

3. Rivers — longest, largest, and the ones papers name

The Nile–Amazon pair (learn together, never merged)

• Nile — the longest river in the world: 6,650 km. It flows through 11 countries (bank answer) and flows north into the Mediterranean Sea. Its main source waters gather in Lake Victoria.
• Amazon — the largest river in the world (by discharge). Length 6,448 km (bank figure). It rises in Peru, crosses the Equator twice, and pours into the Atlantic Ocean. Its dolphins are pink — a favourite odd-one-out fact.
• Yangtze — the longest river of Asia: 5,494 km. It flows through China alone and pours into the East China Sea; Shanghai stands on it (Chapter 1).
• Hwang Ho (Yellow River) — the “Sorrow of China” (Chapter 1): it carries yellow silt from the Loess Plateau.
• Missouri — the longest river in North America (bank answer; the Missouri–Mississippi system together). The Mississippi itself is the system’s famous name — if a paper offers only “Mississippi” for North America’s longest, it is the same system.
• Volga — in Russia, the longest river of Europe; it rises in the Valdai Hills (Chapter 1) and pours into the Caspian Sea.
• Danube — rises in Germany, pours into the Black Sea; Belgrade and Budapest (“Pearl of the Danube”) stand on it.
• Mekong — the “Mother of Rivers” of the banks (Chapter 1); it is disputed between Thailand and its neighbours in bank questions.
• Indus — 3,180 km in total (Pakistan Studies Chapter 13). It meets the Kabul River at Attock. The Indus Waters Treaty questions in the banks (which river was “surrendered” by Pakistan, the Baglihar Dam on the Chenab) belong to this river system — the treaty itself is taught in Pakistan Studies, the river facts here.
• Roe River, Montana, USA — the shortest river in the world: 61 metres (bank figure, asked repeatedly, length and place together).
• Tigris and Euphrates — the Mesopotamian pair (Chapter 1): both rise in Türkiye, flow through Syria and Iraq, and join as the Shatt al-Arab. When a paper asks the Middle East’s longest river and offers the pair as one option, the pair is the intended answer — but the longest single river of the region is the Euphrates alone (about 2,800 km).
• Usumacinta — the longest river wholly in Central America, flowing through Guatemala and Mexico. The Rio Grande is longer overall, but it forms the US–Mexico border, so it is not the wholly-Central-American answer.
• Kızılırmak (Red River) — the longest river in Türkiye, flowing entirely within the country through central Anatolia to the Black Sea.
• Karun — the longest river in Iran (about 950 km), rising in the Zagros Mountains and flowing through Khuzestan to the Arvand Rud; it is also Iran’s only navigable river and its highest-discharge river.
• Zambezi — the river of Victoria Falls (Section 8).

River table for revision

4. Lakes — area, surface, volume, depth: four different champions

• Caspian Sea — the largest lake in the world (by area). It is called a “sea” but it is a lake — landlocked, salty, bordered by five littoral states (Russia, Kazakhstan, Turkmenistan, Iran, Azerbaijan). Its area is the one figure papers disagree on: see Traps.
• Lake Superior — the largest freshwater lake in the world by surface area. It is the largest of the five Great Lakes of North America — Superior, Michigan, Huron, Erie, Ontario (mnemonic in Section 10) — shared by the USA and Canada (the USA shares four of the five; Michigan lies wholly in the USA).
• Lake Baikal, Siberia, Russia — the deepest lake in the world: 1,642 m. It is also the oldest lake (25–30 million years) and the largest freshwater lake by volume — about a fifth of the world’s unfrozen fresh surface water, more than all the Great Lakes combined.
• Lake Tanganyika — the second-deepest lake (1,470 m) and the longest freshwater lake in the world (Burundi, DR Congo, Tanzania, Zambia).
• Lake Victoria — the largest lake in Africa, the world’s largest tropical lake, and the second-largest freshwater lake by surface area — but shallow (about 80–84 m deep). It is the Nile’s source lake (Section 3).
• Lake Titicaca (Peru–Bolivia) — the highest navigable lake in the world.
• Dead Sea — between Israel and Jordan: a salt lake and the lowest point on Earth below sea level. It is called a “sea” and is a lake — the same naming trap as the Caspian.
• Lake Eyre — the largest lake in Australia (bank answer for the dry continent’s lake question).
• Pakistan’s lakes (bank answers, taught in full in Pakistan Studies Chapter 13): Manchar (Manchhar) — the largest lake in Pakistan and its largest freshwater lake; Keenjhar — the largest man-made lake in Pakistan; Saif-ul-Maluk and Kallar Kahar are the named lakes papers ask by district and province.

5. Deserts — hot, cold, and the “friendly” one

• Sahara — the largest hot desert in the world, in Africa. It is the banks’ answer to “largest desert of the world”. If Antarctica is offered, see Traps — it is the larger desert overall, being a cold desert.
• Gobi — in Mongolia (and northern China), a cold desert (Chapter 1: a desert means under 10 inches / 25 cm of rain a year).
• Kalahari — southern Africa (Botswana, Namibia, South Africa). Namib — the coastal desert of Namibia (“Nambian” in bank spellings). Atacama — Chile, the driest place on Earth among the named deserts.
• Arabian Desert — the peninsula’s desert (Rub’ al Khali and Al-Nufud, Chapter 1). Syrian Desert — Syria, Jordan, Iraq, Saudi Arabia. Karakum — Turkmenistan. Taklamakan — western China (Xinjiang).
• Thar — the “Friendly Desert”, shared by Pakistan and India (Rajasthan) — Chapter 1’s nickname, asked as “which desert is called friendly”.
• Dasht-e-Lut — in Iran, the hottest desert in the world (Chapter 1). Kharan — in Balochistan, Pakistan, the desert papers ask by province. Great Sandy Desert — in Australia.
• The continent with no desert is a bank question in its own right — the answer papers key is Europe (Antarctica’s ice desert aside, the question means hot deserts; Europe has none).

6. Straits & canals — the choke points

A strait is a narrow natural passage between two landmasses joining two larger waters. Papers ask straits in exactly two forms — what it connects and what it separates — so every entry below gives both.

The canals

• Suez Canal — Egypt, opened 1869, built by the French engineer Ferdinand de Lesseps. It connects the Mediterranean Sea and the Red Sea. Length: the banks’ dominant answer is ~170 km (variants 162.5 km and 169.5 km appear — see Traps). Nationalised by Egypt on 26 July 1956 (Nasser); closed 1967–75 after the Arab–Israel war. Britain acquired its controlling interest in 1875.
• Panama Canal — opened 1914. It connects the Atlantic and Pacific Oceans (and so links North America with South America). France started its construction; it is under the control of Panama. Length in the banks: 50.72 miles (about 82 km).
• Grand Canal, China — the longest canal in the world (bank answer): Beijing to the south, about 1,794 km (Chapter 1).
• Kiel Canal — in Germany, joining the North Sea to the Baltic Sea. (Pakistan’s own longest canal, the Lloyd Canal, is a bank answer in the same set — taught in Pakistan Studies.)

7. Islands & peninsulas

• Greenland — the largest island in the world. Second: New Guinea; third: Borneo (bank answer). Sumatra and Java follow among the great islands of Indonesia; Honshu is the largest island of Japan (Chapter 1).
• Sicily — the Mediterranean island papers ask for its active volcano, Etna — and it is the largest island in the Mediterranean Sea. Sardinia is Italy’s second island, and the Mediterranean’s second-largest.
• Longest coastline in Asia: Indonesia — the archipelago of thousands of islands gives it Asia’s longest coast; the world’s longest coastline overall is Canada’s (see the master table). Cyprus — the divided eastern-Mediterranean island (Chapter 1: north backed by Türkiye, south by Greece).
• Astola — the largest island found in Pakistan (bank answer, asked repeatedly). Diego Garcia — the Indian Ocean island of the banks’ questions. Socotra — the island of Yemen, in the Arabian Sea off the Horn of Africa, famous for its unique flora.
• Arabia — the largest peninsula in the world (bank answer, asked repeatedly). The other peninsulas papers name: Iberian (Spain–Portugal), Balkan, Korean, Kamchatka (Russia), Yucatan (Mexico), Crimean (disputed between Russia and Ukraine), and Florida.
• Manora — the largest peninsula found in Pakistan (bank answer — do not confuse it with Astola: Astola is the island, Manora the peninsula).
• The Italian Peninsula and the Balkan Peninsula are separated by the Adriatic Sea (bank question, with Venice as the landmark city).

8. Mountains & waterfalls

Peaks and ranges

• Mount Everest — the highest mountain peak in the world: 8,848 m (Chapter 1 exam rule: tick 8,848 if it is offered; the re-measured figure is 8,848.86 m). It stands in Nepal, in the Himalayas; its Nepali name is Sagarmatha.
• K2 (Godwin-Austen / Chogori) — the second-highest peak in the world: 8,611 m, in the Karakoram (Pakistan Studies Chapter 13). Nanga Parbat is the Himalayan giant papers ask by height and place in the same set.
• Kilimanjaro — the highest mountain in Africa, in Tanzania. Aconcagua — the highest in South America. Elbrus — the highest peak of Russia, and the highest peak of Europe. Mont Blanc — the highest peak of the Alps (Western Europe) — see Traps for the Elbrus/Mont Blanc split.
• Andes — the longest mountain range in the world (South America).
• Glaciers: Siachen — the largest glacier outside the polar regions (bank answer); Lambert (Antarctica) — the largest glacier in the world overall; Batura — the second-largest glacier of Pakistan, 57 km (bank figure). Longest, not largest: Fedchenko Glacier, Tajikistan — 77 km, in the Pamir Mountains — the longest glacier outside the polar regions; Siachen, at 76 km, is the second-longest.
• The “Third Pole”: the Hindu Kush Himalaya (HKH) region — called the Third Pole because it holds the largest reserve of ice and snow outside the Arctic and Antarctic, across eight countries including Pakistan, feeding ten major Asian river systems including the Indus (PMS Screening 2026 pack residue, added 2026-11-03; ICIMOD standard verified).

Waterfalls

• Angel Falls, Venezuela — the highest waterfall in the world: 979 m, in Canaima National Park, falling from the flat-topped Auyan-Tepuí. Second: Tugela Falls, South Africa — 948 m.
• Niagara Falls — between the USA and Canada (the border waterfall of the banks). Victoria Falls — between Zimbabwe and Zambia, on the Zambezi River (discovered for Europe by David Livingstone in bank questions).
• Jog Falls (India) — the highest waterfall in India of the banks’ questions. Highest waterfall in Europe: Vinnufossen, Norway — about 860 m.
• Kunchikal Falls — the highest waterfall in India by the standard figure: about 455 m, on the Varahi River in Karnataka (Shivamogga district), falling in tiers, not one plunge. Trap: Nohkalikai Falls (Meghalaya, about 340 m) is India’s highest plunge waterfall — the booklet key that names it for “highest in Asia” confuses plunge with overall height; the mock’s “highest in Asia” wording is the mock’s phrasing for the same 455 m figure, and this chapter teaches the verified India claim.

8A. Retrospective — the 2025 largest-cities year (origin year 2025) 🆕 2025

This table is a retrospective fold-in from the Current Affairs retrospective (coverage-audit item Slice 70, 2026-11-01): the one superlative this chapter’s master table had never carried — the world’s largest city — changed its answer in 2025, and the next paper round can ask the new answer. Bank evidence: the gk360 monthly Current Affairs bank (17 files / 2,012 questions; script hidden_files/goldmine-notes-count-gk02-2025super.py over the 12 × 2025 files / 1,416 questions — 49 superlative-pattern rows, 2 tight rows cited below, the rest examined and stated, not counted). Every row is verified against a standard source named in the chapter footer; where the bank’s wording is loose, the verified wording is taught. No 🔁/⭐ mark is claimed for this table itself: one year’s CA-bank rows are not a multi-paper repeat pattern.

The source is the UN’s World Urbanization Prospects 2025, published by the UN Department of Economic and Social Affairs (Population Division) in November 2025 — the first major revision since the 2018 edition, and the first to use the harmonised Degree of Urbanisation methodology (built on the Global Human Settlement Layer), which measures urban centres consistently across countries instead of following each country’s own city definition. That measurement change is half the story: Jakarta did not suddenly grow past Tokyo in a year — the new measure counts Jakarta’s whole connected urban area, where the old lists counted a narrower city.

Three context figures complete the picture: 33 megacities (10 million or more) exist in 2025, up from just 8 in 1975; 9 of the world’s 10 largest cities are in Asia, Cairo the exception; and 45% of the world’s 8.2 billion people lived in cities in 2025, up from one in five in 1950.

Examined and not taught (stated, not counted): the bank’s São Paulo row (November id 67 — “largest city in the Americas, 18.9 million”) is held, not taught — no WUP 2025 top-list reporting corroborates an 18.9 million Americas lead, and Mexico City exceeds that figure on most measures, so the figure cannot be taught as the Americas rank; the Curaçao row (November id 44 — smallest nation ever to qualify for the FIFA World Cup) is a sports record for GK-06’s sports year, not this chapter; the Markhor sculpture row (November id 27, Kaghan) is already taught in GK-09 Section 3H; the Chinese-loans rows (November ids 3/111, Pakistan the largest recipient) belong to GK-10/PS-14, not duplicated here; the Tianshan Shengli Tunnel row (December id 13, 22.13 km, opened 26 December 2025) and the Motuo/Yarlung Tsangpo dam row (July id 99, construction from 19 July 2025, ~60 GW, ~300 billion kWh a year) are already taught in EDS-08 Section 7A, the 2025 science year, and are cross-linked, not duplicated; the compressed-air storage row (January id 3, China) belongs to EDS-09 Section 8B’s 2025 energy year (Yingcheng); the Vizhinjam cargo-vessel row (June id 27) is held — the vessel is unnamed in a single bank row and unverified; the Hong Kong black-rainstorm row (August id 19, four record signals 29 July–5 August 2025) is a weather-warning record, not a geographic feature, and is a candidate for GEO-02’s weather sections, not this chapter; the Barbados smallest-snake row (August id 194) is a nature record for EDS, not GK-02; the remaining pattern rows are sports records (Kohli, Rashid Khan, Messi), richest-man rows, population totals, disease counts and volcano/flood rows already served from GK-06, GK-07, GK-09, EDS-04 and GEO-02 Section 2A–2F respectively.

10. Most-asked facts (from our verified past-paper banks)

• The Suez Canal’s two seas (Mediterranean and Red) — asked more often than any other single fact in this topic, in a dozen wordings.
• The Strait of Malacca in both forms — what it separates (Malaysia–Indonesia) and what it connects (Andaman Sea–South China Sea).
• The Nile–Amazon longest/largest split — papers deliberately offer one when they ask the other.
• Baikal as deepest lake, Caspian as largest lake, Superior as largest freshwater lake — three questions that look identical until the qualifier is read.
• Sahara as largest desert (with Antarctica as the trap option), Greenland as largest island, Arabia as largest peninsula, Astola as Pakistan’s largest island.
• Everest’s height and place, Angel Falls’ place (Venezuela), Niagara’s two countries, Victoria Falls’ two countries and river.
• Panama 1914, Atlantic–Pacific and Suez 1869, nationalisation 1956 — the two canal dates papers repeat.
• The 2025 largest-cities year (Section 8A) is the chapter’s retrospective layer, not a new repeater: its 2 cited rows come from the gk360 monthly CA bank’s November 2025 file, and the next paper round asks them exactly the way the CA bank does — city, figure, rank. The old Tokyo answer is the trap this table exists to disarm.

11. Traps & confusions

• Longest vs largest river: Nile = longest, Amazon = largest (discharge). If the question says “largest river” and offers both, tick Amazon; if it says “longest”, tick Nile.
• Longest vs largest glacier: the same adjective trap — Fedchenko (77 km) is the longest glacier outside the polar regions; Siachen is the banks’ largest outside the polar regions, and at 76 km only the second-longest. Read the adjective, not just the noun.
• Sahara vs Antarctica: Sahara is the largest hot desert and the banks’ answer to “largest desert”. If Antarctica is among the options and the question says only “largest desert”, tick Antarctica — it is the largest desert of all (Chapter 1’s tip, repeated because it is tested every cycle).
• Diamond producer — volume vs value: by volume, Russia; by value, Botswana. A paper that keys Botswana is answering the value question; one that asks for the largest producer without qualification wants Russia (Grand Mock 15, Q74, mock-corrected).
• “Spice Island”: Zanzibar is the classic Spice Island. Madagascar is the spice-producing island the mocks fall back on when Zanzibar is not among the options (Grand Mock 15, Q54; mock-only rows — Madagascar is taught here as the option-set fallback, not as the standing title, which belongs to Zanzibar).
• Caspian’s area: our banks print 394,299 sq km for the world’s largest lake; modern atlases print about 371,000 sq km. The name (Caspian) is never in doubt — only the area figure moves. Tick the figure the options carry.
• Suez Canal length: banks print ~170 km most often, with 162.5 km and 169.5 km in other papers. Tick 170 km if it is offered; the seas it connects never vary.
• Highest plateau: banks key Pamir. Atlases call the Tibetan (Qinghai–Tibet) Plateau the highest and largest plateau region. Papers follow the banks — tick Pamir when the question is phrased as “highest plateau”.
• Elbrus vs Mont Blanc: Elbrus (Russia) is the highest peak of Europe; Mont Blanc is the highest of the Alps (Western Europe). Read which region the question names.
• Superior vs Baikal: Superior = largest freshwater lake by surface area; Baikal = deepest and largest by volume. The qualifier is the whole question.
• Panama’s two links: the canal links two oceans (Atlantic–Pacific) and, in the banks’ other wording, two continents (North–South America). Both wordings are asked; both answers are “Panama Canal”.
• Astola vs Manora: Astola = island of Pakistan; Manora = peninsula of Pakistan. Papers swap the two nouns deliberately.
• Missouri vs Mississippi: banks key Missouri for North America’s longest river. Mississippi is the same river system’s famous name — if only Mississippi is offered, it is the intended answer.
• Angel Falls’ river: one bank paper keys “Carrao”; standard references give the Churún River (a tributary of the Caroní). The place (Venezuela) and height (979 m) never vary — answer those, and treat the river name as the unstable detail.
• Dead Sea and Caspian Sea are lakes in spite of their names — and both are asked precisely because of that.
• “Largest island” vs “largest island of Pakistan”: world = Greenland; Pakistan = Astola. The qualifier “of Pakistan” changes the answer completely.
• “Second-largest” chains: second-smallest continent = Europe; second-deepest lake = Tanganyika; second-highest waterfall = Tugela; second-highest peak = K2; second-largest ocean = Atlantic. Papers love the second-place answer because students only memorise the first.
• Largest city — Tokyo is the old answer, Jakarta the 2025 one (Section 8A): any book or paper printed before November 2025 keys Tokyo; the UN World Urbanization Prospects 2025 keys Jakarta (41.9m), then Dhaka (36.6m), then Tokyo (33.4m). If the question names the WUP 2025 or asks for the current largest city, tick Jakarta; if it asks for the city proper (not the urban area), Tokyo is about 14 million — a different measure, not a contradiction. The bank’s “nearly 37 million” for Dhaka is the rounded form of the taught 36.6 million; the bank’s São Paulo 18.9 million Americas-lead row is held unverified and is not taught (see Section 8A).

12. Memory tricks

• “Nile is LONG, Amazon is LARGE”: long and large are different words for a reason — Nile takes length, Amazon takes volume. Say the pair together and you will never swap them.
• HOMES for the Great Lakes: Huron · Ontario · Michigan · Erie · Superior — west to east, the lakes spell a word you already know.
• “Caspian is the CAP, Baikal is the BOTTOM, Superior is the SURFACE”: cap = largest area, bottom = deepest, surface = largest freshwater surface. Three caps, three answers.
• The Turkish Straits chain (from Chapter 1): Black Sea → Bosphorus → Marmara → Dardanelles → Aegean → Mediterranean — walk the water westward and the straits name themselves in order.
• “Suez: Med to Red, 1869” and “Panama: two oceans, 1914” — one line each, date and link together, because papers ask the pair as a pair.
• “Malacca separates M and I, and joins A and S”: Malaysia–Indonesia separated; Andaman–South China joined.
• “Greenland is GREEN on the map and GREAT in size”: the largest island carries the superlative in its own first letter — G for Greenland, G for greatest island.
• “Angel is highest, Tugela is second, Niagara is famous”: height, runner-up and fame are three different questions — learn which waterfall owns which.
• “Jakarta–Dhaka–Tokyo, 42–37–33”: the 2025 largest-cities ladder in one breath — J-D-T down the alphabet of size, figures rounded to the nearest million (41.9 / 36.6 / 33.4).

13. Visuals (site build specs)

• MAP — The world’s superlatives: world map with callouts for Nile, Amazon, Yangtze, Caspian, Baikal, Superior, Sahara, Gobi, Greenland, Arabia, Everest, Angel Falls — placed at the head of Section 2 as the chapter’s orientation graphic.
• DIAGRAM — The Turkish Straits chain: Black Sea → Bosphorus → Sea of Marmara → Dardanelles → Aegean Sea, with the Suez and Panama canals as inset route diagrams — placed in Section 6.
• INFOGRAPHIC — Longest vs largest: side-by-side Nile/Amazon (length vs discharge) and Caspian/Superior/Baikal (area vs surface vs volume), the two distinctions Section 1 warns about — placed in Section 1.
• TABLE GRAPHIC — Straits at a glance: the Section 6 strait table rendered as a sortable revision card (connects / separates columns) — placed at the end of Section 6.
• BAR CHART — The 2025 largest-cities ladder: Jakarta 41.9m, Dhaka 36.6m, Tokyo 33.4m, with the old Tokyo-#1 ranking shown struck through beside it and the Degree of Urbanisation note underneath — placed in Section 8A.

14. Practice this topic

• Practice set: 771 verified past-paper questions in the PPSC + FPSC banks are tagged to this topic’s sub-topics (rivers 89; lakes 91; deserts 51; straits & canals 108; islands & peninsulas 62; mountains & waterfalls 84; other superlatives 286) — the site serves them as this chapter’s practice set, with the IBES World Geography and General Knowledge capsule questions behind them. Note for the build: the practice set is filtered by the topic’s subject+topic tags at serve time, so Indus Waters Treaty questions serve from the river-system tag, Pakistan-lake questions from the lakes tag, and the handful of non-geography superlative strays in the generic bucket (a greatest-university question, a software-company question) are excluded by that filter.
